Primitivity testing in free group algebras via duality

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 6, June 2026.
Abstract Let K$K$ be a field and F$F$ a free group. By a classical result of Cohn and Lewin, the free group algebra KF$K\left[F\right]$ is a free ideal ring (FIR): a ring over which the submodules of free modules are themselves free, and of a well‐defined rank. Given a finitely generated right ideal I⩽KF$I\leqslant K\left[F\right]$ and an element f∈I$f\

KONSTRUKSI LEXICOGRAPHIC UNTUK MEMBANGUN KODE HAMMING (7, 4, 3) [PDF]

open access: yes, 2009
Hamming code can correct single error in massages transmission. Hamming codes can be constructed by Lexicographic codes. Lexicographic construction is a greedy algorithm that produces error correcting codes known as lexicographic codes.

Lexicographic decomposition of preferences

open access: yes, 2013
International audienceThe Ordinal Lexicographic Model, based on the lexicographic sum of relations, provides an explanation to intransitivities in preferences as shifts in choice criteria.

Hamiltonian Decomposition of Lexicographic Products of Digraphs

open access: yes, 1998
We partially resolve a conjecture of Alspach, Bermond, and Sotteau by showing that the lexicographic product of two hamiltonian decomposable digraphs, the first of odd order, is itself hamiltonian decomposable in ...

Prudent Rationalizability in Generalized Extensive-Form Games [PDF]

open access: yes
We define an extensive-form analogue of iterated admissibility, called Prudent Rationalizability (PR). In each round of the procedure, for each information set of a player a surviving strategy of hers is required to be rational vis-a-vis a belief system ...

Stochastic Games with Lexicographic Reachability-Safety Objectives

open access: yes, 2020
We study turn-based stochastic zero-sum games with lexicographic preferences over reachability and safety objectives. Stochastic games are standard models in control, verification, and synthesis of stochastic reactive systems that exhibit both randomness

l. GENERATING ALL SUBSETS OF {1,..., z} IN LEXICOGRAPHIC ORDER

open access: yes, 1986
On the basis ol a backtrack procedure for lexicographic enumeration of all subsets of a set of n elemcnts, we giue an algorithm both for determining all bases consisting offunctions from a giaen complete set in a considered sabset of the set of k-ualued ...

Conditions for generic initial ideals to be almost reverse lexicographic

open access: yes, 2008
Let I be a homogeneous Artinian ideal in a polynomial ring R=k[x1,…,xn] over a field k of characteristic 0. We study an equivalent condition for the generic initial ideal gin(I) with respect to reverse lexicographic order to be almost reverse ...
